Collapsible Pocket Door Frame With Folding Cross Braces for Fast Installation

Solution Overview

Problem

Existing prefabricated pocket door frames require assembly, mechanical fasteners, and professional expertise for installation, and cannot be collapsed to fit within an 8-foot package for efficient shipping and storage.

Innovation Solution

A collapsible pocket door frame design with hingedly connected transverse cross braces that allow expansion from a collapsed to an installed position in a single movement, without additional fasteners or expertise, using materials like wood, polymers, or metals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the pocket door frame is preassembled to ensure proper alignment and orthogonality, then installation quality is improved, but the frame cannot be collapsed to fit within an 8-foot package for efficient shipping and storage

Engineering Contradiction:
Core Design Contradiction:
Manufacturing precisionVSLength of moving object

Solution Approach 1:

The cross braces are divided into two separate components (first cross brace component and second cross brace component) that can be collapsed against each other during shipping, then assembled at the installation site to form the complete cross brace structure

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The hinged connections are pre-configured during manufacturing to ensure that when the cross brace components are assembled on-site, they automatically achieve the correct orthogonal alignment and orientation without requiring additional adjustment or fasteners

Inventive Principle:
Principle #10Preliminary action

2Length of moving object

If the pocket door frame is collapsed to fit within an 8-foot package, then shipping and storage efficiency is improved, but assembly and mechanical fasteners are required during installation

Engineering Contradiction:
Core Design Contradiction:
Length of moving objectVSDevice complexity

Solution Approach 1:

All necessary connection features, hinged connections, and alignment mechanisms are pre-configured during manufacturing of the cross brace components, so that on-site assembly requires only simple connection without additional fasteners or complex adjustment procedures

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The hinged connections and component geometry are designed to self-align and self-assemble during installation, eliminating the need for professional expertise, additional fasteners, or complex assembly procedures

Inventive Principle:
Principle #25Self-service

3Stability of the object's composition

If the pocket door frame uses traditional assembly methods with multiple fasteners, then structural stability is improved, but installation time and professional expertise requirements increase

Engineering Contradiction:
Core Design Contradiction:
Stability of the object's compositionVSLoss of time

Solution Approach 1:

The hinged connections and component interfaces are pre-engineered during manufacturing to provide inherent structural stability and alignment, eliminating the need for additional mechanical fasteners and complex assembly steps during installation

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The cross brace components are designed to self-stabilize and self-align through their hinged connections and geometric configuration, providing frame stability without requiring professional adjustment or multiple fastening operations

Inventive Principle:
Principle #25Self-service
